How many atoms can a Carbon atom potentially bind to?

Back

4

Front

Why are insertion and deletion (frameshift) mutations so harmful?

Back

They change all of the codons from the mutation on down the line, which changes the amino acid sequence.

Front

What segment of nucleic acid travels from the nucleus to the ribosome?

Back

Messenger RNA.

Front

What is the term for the change from THEBIGFATREDCATSAT to THEBIGFATREDATSAT?

Back

Deletion.

Front

What are the two components that make up the backbone of DNA?

Back

Sugar & Phosphate.

Front

What is the role of messenger RNA (mRNA) in protein synthesis?

Back

mRNA carries the genetic information from DNA to the ribosome for protein synthesis.

Front

What is a frameshift mutation?

Back

A mutation that occurs when nucleotides are inserted or deleted from the DNA sequence, altering the reading frame.

Front

What is the function of transfer RNA (tRNA)?

Back

tRNA transports amino acids to the ribosome during protein synthesis.

Front

What are nucleotides?

Back

The basic building blocks of nucleic acids, consisting of a sugar, a phosphate group, and a nitrogenous base.

Front

What is the difference between DNA and RNA?

Back

DNA is double-stranded and contains deoxyribose sugar, while RNA is single-stranded and contains ribose sugar.
